Abstract

''FACA ROTATIVA DE BAIXO ATRITO''. Trata-se de uma faca operada por energia que compreende uma estrutura de suporte de lâmaina, suportando uma lâmina anular para rotação em torno de um eixo central. A lâmina e a estrutura de suporte de lâmina são engatáveis ao longo de linhas de contato de sustentação, as quais se encontram reciprocamente espaçadas em uma direção paralela ao eixo, de tal forma que a lâmina seja estabilizada tanto radial, quanto axialmente, durante a operação da faca. A estrutura de suporte de lâmina compreende um elemento fendido de alojamento para lâmina, que pode ser radialmente expandido e contraído, a fim de receber a lâmina. O elemento fendido de alojamento para lâmina e a lâmina se engatam ao longo de linhas de contato de sustentação, relativamente curtas, que servem para minimizar o atrito e o aquecimento da lâmina quando a faca se encontra em operação. Os locais de sustentação se encontram reciprocamente espaçados, tanto de forma circunferente em torno do perímetro da lâmina, quanto na direção ao eixo, de tal forma que o posicionamento da lâmina seja estabilizado durante a operação da lâmina.'' LOW-FRICTION ROTATING KNIFE ''. It is an energy-operated knife that comprises a blade support structure, supporting an annular blade for rotation around a central axis. The blade and blade support structure are interlockable along support contact lines, which are reciprocally spaced in a direction parallel to the axis, such that the blade is stabilized both radially and axially during operation of the knife. The blade support structure comprises a slotted blade housing element, which can be radially expanded and contracted in order to receive the blade. The split blade housing element and the blade engage along relatively short support contact lines, which serve to minimize friction and heating of the blade when the knife is in operation. The support locations are reciprocally spaced, both circumferentially around the perimeter of the blade, and towards the axis, in such a way that the positioning of the blade is stabilized during the operation of the blade.
